The United States Small Business Administration (SBA) is revising the size standards for 13 industries in North American Industry Classification System (NAICS) Sector 22, Utilities. Specifically, SBA has increased receipts based size standards for three industries and changed the basis for measuring business size from megawatt hours to number of employees for the 10 electric power generation, transmission, and distribution industries. In addition, SBA is removing Footnote 1 from SBA's Table of Size Standards that applies to all of the NAICS codes in electric power generation, transmission, and distribution. As part of its ongoing comprehensive size standards review, SBA evaluated all megawatt hour and receipts based size standards for industries in NAICS Sector 22 to determine whether they should be retained or revised. SBA did not review the employee based size standard for Natural Gas Distribution, NAICS 221210, in this rule, but will review it in the near future with other employee based size standards.
